How Does Odometer Correction Work?

Odometer correction, also known as mileage programming, typically involves accessing the electronic control unit (ECU) or instrument cluster of a vehicle to modify the stored mileage data. The exact process can vary depending on the make, model, and year of the vehicle.

In many modern vehicles, mileage data is stored digitally in the vehicle's ECU or instrument cluster. Odometer correction tools and software are used to communicate with these electronic systems, allowing technicians to adjust the stored mileage values.

The process may involve connecting diagnostic equipment to the vehicle's onboard diagnostic (OBD) port or directly accessing the ECU or instrument cluster through other means. Technicians then use specialized software to read and modify the mileage data as required.

It's important to note that odometer correction should only be performed by trained professionals with the necessary expertise and equipment. Attempting to alter mileage data without proper knowledge and tools can result in damage to the vehicle's electronic systems and may also be illegal in many jurisdictions.

It is illegal to alter your car’s mileage without proper documentation. At an event you sell your vehicle, you must disclose this information to potential buyers. All customers must provide a legitimate reason for this service. Our services require a disclaimer form to be filled out prior to work being done on the odometer. You will see the Disclaimer form at the end of check out. Add items to the shopping cart, and then after the order is placed on the website, you will see the form and will have a place to add your signature.

Always consult with reputable automotive professionals or service providers for assistance with odometer correction, and ensure that any modifications comply with local laws and regulations.
